Application filed May 4, 1914. Serial No. 836,368.

new and useful Improvements in Ironing- Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My invention. relates to ironing machinery and it has for its object to improve the construction of the class of machines known as bosom presses. and embodying, generally, a steam chest and a platen which are relatively movable to bring one into engagement with the other and thereby to engage and press the bosom of a shirt. Among other purposes, the invention contemplates combining the elements of a machine of this type in a novel manner to obtain more eifective results, both as to the finish of the shirt, and speed of operation. More specifically, the invention has for its purpose to provide an improved mechanism for controlling the position of the movable pressing member or platen so as to exert a maximum pressure thereon and also to aflord a regular steady movement as it is brought into engagement with the stationary member. Another advantage of the invention lies in the ease and rapidity with which the movable member or platen may be actuated away from engagement with the stationary member. To these and other ends the invention resides in certain improvements and combinations of parts all as will be hereinafter more fully explained, the novel features being pointed out in the claims at the end of the specification. 4 1

In the drawings:

Figure 1 is a front elevation, partly in section, of a bosom press, showing the application of my improvements to the same;

Fig. 2 is a sectional view on the line 2 2 of Fig. 1;

Fig. 3 is an end elevation, with parts in section;

Fig. 4. is a sectional view 44 of Fig. 1;

Fig. 5 is an enlarged detail plan view of the fluid pressure cylinder;

Fig. 6 is a transverse sectional view, and

on the line Fig. 7 is a vertical sectional view taken centrally of the machine and showing the operating lever.

Similar reference characters in the several figures indicate the same parts.

In the construction shown in the present embodiment, l designates a portion of the frame of the machine upon which is mounted the stationary heated bed or chest 2, to which heating fluid may be supplied in any convenient manner. The machineis further provided with a vertically movable pressing member or platen 3 which is adapted to be elevated into engagement with the stationary bed 2, and in the present construction I have illustrated a known type ofmachine including a rotary carrier 4 provided with a pair of platens 3 so that while one of the platens is in pressing relation with the heated chest. the operator may be positioning a shirt on the other. Each platen is mounted on a support 5 which is vertically movable within a guide 6, and arranged on the frame of the machine is a plunger 7 adapted to cooperate with the lower ends of the supports 5 to actuate the same upwardly. The plunger 7 is moved vertically by means of a lever 8 which is pivoted at 9 and has its inner end 10 arranged to freely engage the lower end of the plunger 7. The opposite end or long,

arm of the lever 8 is pivotally connected to the lower end of a connecting rod 10 the upper end of which is mounted on a cross head 11 by a pivotal connection 12. The cross head 11 carries the tubes 13 which telescope within the stationary tubes 14 arranged on the frame, and 15 designates springs which are arranged within the telescoping sections for a purpose that will appear presently. The tension of the springs 15 can be adjusted by means of movable stops 16. The cross head 11 carries a piston rod 17 movable within the cylinder 18 and provided at its upper end with the piston 19.

sitioned on the platen, the carrier 4 is rotated to bring the platen into vertical alinement with the steam chest 2, in which position the support 5 is disposed above the plunger 7. Thereupon fluid pressure is admitted to the cylinder 18, causing downward movement of the cross head 11 and of the outer end of the lever 8. This serves to move the inner end of the lever upwardly, elevating the plunger 7 and thereby raising the platen into pressing engagement with the steam chest or bed. Upon releasing the fluid pressure, the weight of the platen and its support, combined with .the action of the springs 15, serves to effect a quick and easy return of the parts to their normal position. While I have disclosed a construction embodying a carrier, with separate platens mounted thereon, it will be understood that the invention is equally applicable to a machine embodying only a single'platen, in which case the lever 8 would operate directly on the platen support, and I intend to cover by this application the operating means by which vertical movement of the platen is effected, including the fluid pressure controlled devices and the arrangement of the lever which operatively connects the latter to the platen.

I claim as my invention:

1. In an ironing machine, the combina-v tion with a stationary bed, of a platen arranged beneath the bed and movable upwardly into engagement with the bed, a support for the platen, a pivotally mounted lever having one end operatively associated with the bottom of said support, a vertically movable frame, a link connecting-said frame with the opposite end of the lever, spring controlled devices operating to hold said frame normally elevated, and a fluid pressure controlled member connected to said frame.
